At the end of a race a runner decelerates from a velocity of 9.00 m/s at a rate of 0.300 m/s2. (a) How far does she travel in the next 16.0 s? m (b) What is her final velocity? m/s

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
